Firstly pull it out of its cavity, then lean it 45degrees to the left (water will drain out) and then 45 degrees to the right. 30 seconds in each position. This should fix it.

Can you hear the pump running? Check for any debris in the bottom of the machine, below the filters. Usually the pump impeller is very close, and its easily jammed with debris or maybe a bit of broken glass etc.
